Ensure 'Tenant Creator' role assignments are periodically reviewed

Description

Perform a periodic review of the Tenant Creator role assignment to ensure that the assignments are accurate and appropriate.

This recommendation should be applied alongside the recommendation "Ensure that 'Restrict non-admin users from creating tenants' is set to 'Yes'".

Rationale

Unnecessary assignments increase the risk of privilege escalation and unauthorized access.

Impact

Verify that the Tenant Creator role is no longer required by any assignments before removal to avoid disruption of critical functions.

1. Go to Microsoft Entra ID.
2. Under Manage, click Roles and administrators.
3. In the search bar, type Tenant Creator.
4. Click the role.
5. Review the assignments and ensure that they are appropriate.

Expected Result

The Tenant Creator role should have no unnecessary assignments. All assignments should be justified and documented.

Remediation

Remediate from Azure Portal

1. Go to Microsoft Entra ID.
2. Under Manage, click Roles and administrators.
3. In the search bar, type Tenant Creator.
4. Click the role.
5. Click the name of an assignment.
6. Check the box next to the Tenant Creator role.
7. Click X Remove assignments.
8. Click Yes.
9. Repeat steps 1-8 for each assignment requiring remediation.

Default Value
